This read-only CucsEquipmentLedOperState field is the 'operState' property of the 'HealthLed' managed object in Cisco UCS Manager's equipment-inventory schema reporting whether the LED hardware itself is operating correctly. This is distinct from what the LED is displaying about the equipment's health, it instead reports on the LED indicator's own operability, so an admin can tell a burned-out LED from equipment that's actually reporting a genuine fault. An OperState reporting the LED itself as inoperable means an admin can't rely on that LED's Color or HealthLedState to judge the blade's actual condition and should check UCS Manager's fault list directly instead.
